In 1991, the Sex Information and Education Council of the United States (SIECUS) developed guidelines for presenting age appropriate, comprehensive sexuality education. This publication reports on a 1993 study, using these guidelines as a framework to assess sexuality education curricula and guidelines in the United States. A survey instrument was sent to each of the state and territorial education agencies. Data analysis suggested that the vast majority of states have developed a strong framework for building comprehensive sexuality education programs; that the states have laws or policies recommending or requiring sexuality education and have developed sexuality education curricula or guidelines to provide program guidance to local school districts; and that these curricula or guidelines include abstinence messages as well as positive and affirming statements about human sexuality. However, many state guides omit sexual behavior topics and exclude topics that are considered controversial, such as sexual orientation and abortion. A series of recommendations, developed by SIECUS, are offered to assist states in enhancing sexuality education. The report concludes by citing the states with the most outstanding sexuality education curricula--Alaska, Iowa, Kansas, and Rhode Island. (LL)
